Anerve poison that blocks acetylcholine receptors on dendrites would a nerve poison that blocks acetylcholine receptors on dendrites would cause continued stimulation of the postsynaptic membrane inhibit the regeneration of acetylcholine for use by the presynaptic terminals inactivate acetylcholinesterase, allowing acetylcholine to persist in the synapse reduce the binding of acetylcholine to its receptors on the postsynpatic membrane cause an immediate and enduring depolarization
